All planning permissions have a number of conditions that will need to be met prior to or during the detailed specification and construction phases. These may involve the resolution of design detail, or may relate to key aspects of the development such as the final agreement of specific colours and materials. Some minor design elements of a proposed development may need to be considered afresh during this stage e.g. the lighting strategy, landscaping, materials and colours.
Monitoring of the post construction environmental impacts of the facility is often required and can be an indicator of the effectiveness of some aspects of the facility design.
